CCNA 2.2 Configure IP addresses, subnet masks, and gateway addresses on Cisco routers and hosts
Configure IP addresses, subnet masks, and gateway addresses on routers and hosts
Configuring the IP address and subnet mask on a Cisco router is done with one easy command.
The gateway address, also referred to as a default route, is the IP address of the next step toward an IP address in a different subnet that isn’t provided by some other route. Setting the default route on a Cisco router is also an easy single commnd.
Configuring these values on a host (as far as the exam is concerned) is more about knowing what values to configure than how to configure them (every operating system has different methods for setting these values anyway). Understanding subnets is the most imporatant aspect of this objective point. Make sure you can tell which IP addresses in a list are included in a subnet and which are outside of a subnet. Keep in mind that the default route for a host must be in the same subnet as the host’s IP address.
